We have been going back through all of our old blog posts and adding tags (which we forgot to do when we first published the posts). Everytime we add tags, though, our subscribers are seeing the post as a "new" post in their RSS feeds. This is a problem because we have been tagging about 25 blog posts per day and it is overwhelming their news feeds with "old" posts. Is there a way to change some setting so that this does not happen?
The blog I need help with is domainnamestrategy.com.
